ANTIFREEZING DEVICE FOR WATER-PIPES.

Specification of Letters Patent.

Patented Mayll, 1918.

Application led March 22, 1917. Serial No. 156,701.

To all 'w/wm'z'z may concern.'

Bc it known that I, JOHN L.' Gnoo, a citizen of the United States, residing at vtalt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Antifreezing Devices for Tater-Pipes; and I do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled inthe art tofwhich it appertains to make and use 'the same.

M invention has for its object to provide extremely simple means for preventg ing water from freezing in water pipes 'eX- posed to cold temperatures7 this end being attained by introducing a salt or other antifreezing medium to the water as it passes through the pipe. l

`With the foregoing general object in view, the invention resides in certain novel features of construction and vuniquecombinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the. accompanying drawings which constitute a part of this application and in which:

Figure l is a perspective view of the invention applied;

Fig. 2 is an enlarged vertical section thereof;

Fig. 3 is a vertical section on the the line of Fig. 2;

F ig. l is a horizontal section on the line 4 4 of Fig. Q.

ln the drawings above brieiiy described, P has reference to the vertical pipe of a lmilding designed to conduct water from the usual eavestroughs to any desired point but usually to a suitable container. Heretol'ore. in freezing ten'iperatures it has been impossible to prevent freezing of the water in pipes such as P with the result that they become clogged with ice so that thc water from the troughs is not properly carried olf. This causes these troughs to overflow aud the water dripping in this manner as wel! as that collecting in said troughs is frozen into ice which causes great trouble particularly when thawing begins. The present invention aims to overcome this difficulty by introducing salt or other antifreezing medium into the water passing downwardly through the pipe. The water treated in this manner will not freeze and since pipes of the character set forth freeze from the bottom up, the conditions above plane of described cannot be caused. The construction employed for introducing the antifreezing medium is preferably in the form described below.

A vertical pipe section l is interposed be tween two sections of the pipe P at anv desired point above the lower end of the latter, said section l being preferably though not necessarily rectangular in horizontal section and havingin one of its sides an opening 2 into which a suitable hopper 3 disl charges, said hopper being located on the exterior of the pipe section l and vhaving a hinged inclined top 4 by means of which it 11i-ay be filled when required. The lower end 5 of hopper 3 inclines downwardly to the pipe section l and is provided on its lower side with a guide or sheath 6 in which a pervious slider 7 is located, the inner end of said slide normally extending across the pipe section l to form a pervious support vfor the salt or the like supplied from the hopper. A suitable ledge 8 is preferably provided in the section l to support the inner end of the slidc 7. i

A gate valve 9 is employed for controlling the amount of salt discharged from the hopper 3, said valve being in the form of a rectangular plate contacting slidably with the exterior of the sect-ionl and located in said hopper, a suitable stem l0 being provided for operating said valve. The valve 9 is guided in its movement by vert-ical langes 1l formed in a unique manner. rllhe two opposed sides 1Q of the hopper 3 are bent inwardly upon themselves near their free edges at 13 to form flanges which are soldered or otherwise secured to the sides .of the section l. and after being bent in this manner said edges of the sides l2 are bent inwardly at right angles to form the flanges ll which are spaced from the section l.

In use. the pipe section l is introduced into the pipe P at a suitable point as indi- -ate l in Fig. l and the hopper 3 is filled with the anti-freezing medium to be employed, the opening 2 being now controlled by the valve 9 to permit the required amount of .salt or the like from the hopper to pass into the section l upon the partition 7 therein. Any water now passing downwardly through the pipe will be prevented from freezing since it is converted into a briny solution and whenever required the hopper 3 may be refilled by opening the top d thereof. luring the Warnier months, when Jshe use or the device is not needed, the slide may be easily ni'ilhdrawn and th faire 9 then closed.

From the foregoing, taken in connection with the accompanying drawings, it will be obvious diet alhough the invention is oi' simple and inexpensive nature, it will be highly7 efficient for the purpose intended. For these reasons, the construction shown constitutes the preferred embodiment of the device but itis to be understood that within the scope of the invention as claimed7 numerous minor changes may be made without sacriricing the principal advanages. Furthermore, the use of the invention is not limited to water pipes such as JChose de scribed but is applicable to anyvv pipe exposed to freezing temperatures.

l claim:

l. The combination `with n water pipe having in one side an opening, of a perrious partition extending across said pipe below said opening for supporting an enti-freezing medium therein in the path of the water passing through said pipe, and a hopper on the exterior of the pipe for supplying said inediuin to seid partition through said opening.

2. The combination with n water pipe inname haring an opening in its side, of a hopper on the exterior of seid pipe discharging into said opening, said hopper haring an inclined bottom equipped with a guide, and a pervious slide in said guide movable across said pipe to support therein an anti-freezing medium supplied by said hopper.

3. The combination with a water pipe haring an opening in its side, of a hopper on the exterior of seid pipe for supplying an anti-freezing medium to seid pipe through said opening, the opposed sides of said hopper having their inner edges bent inwardly io forni attaching ianges secured to the pipe and then again inwardly to Jorin vertical guide iianges located in the hopper and spaced from said pipe, a Valve slidably mounted between said pipe and flanges for controlling the aforesaid opening, and Ineens in the pipe Jfor supporting the anti-freezing medium discharged Jfrom the hopper.

ln testimony whereoi` l hare hereunto set my hand in the presence of two subscribing p witnesses.
